diff question.

[charliebrown]

Hey guys, I'm new to this forum business but i have a couple of problems concerning my rear diff.

I have a 4.2 TD GU DX 99' model patrol ute. the car was leant out to my dad and he apparently did a reverse rolling start and heard a loud noise. he drove it home about 150kms. i got it back and it was making a noise from the rear end. It sounded like a uni so i replaced both of those and then did the rear control arm bushes as well.

it didnt fix the problem so i have now pulled the rear centre out. i had a look inside and the housing was scratched up pretty bad in one area. the crown wheel has some small 3-4mm chunks out of it. the pinion is missing 2-3inches off 4 teeth. i dont know but a rebuild sounds like big trouble if you dont get all the tolerances and backlash right.

I can not find a rear centre anywhere. its a 4.11 ratio and as ive been looking around im getting confusing info. can a GQ rear 4.11 fit in? i have a very strong lsd and would like to put it into a new centre but not sure how hard that is. Apart from getting another rear diff centre, have i got any other options?

ive attached some photos of the centre. (sorry bout the quality)

G'day Charlie

Mate we like folks to start in teh INtroduction section adn post an intro so members can see who they are talking too. Please head over and do an intro.

Re your question.

As long as you have a H233 rear diff and not a H260 then a GQ centre will go straight in. some of the Utes ran the H260 which is a Bigger housing.

Post a pic and we'll have a look.

They might be too large to upload, you'll see on that upload page what the size restrictions are.

is there some way to change the photos?

[MudRunnerTD]

download an App on your phone called Tappatalk. then take a pic with your phone and post it here.

HG41 means H233b diff housing [small one] with 4.1 ratio

HH41 means H260 diff housing [big one] with 4.1 ratio


GQ centre fits straight in
if your not sure of ratio ... divide the number of crownwheel teeth by the number of pinion teeth to get your answer.
